Now imagine that the murderers are some of the most powerful and celebrated members of society, free to boast about their crimes with impunity.

That’s the premise of Joshua Oppenheimer’s new documentary, The Look of Silence. A companion piece to his previous film The Act of Killing, The Look of Silence confronts the perpetrators of the Indonesian genocide of 1965 from the perspective of its victims today, who are determined to learn the unspeakable truth of their past.

Reason TV spoke with the film’s director, Joshua Oppenheimer about the psychology of genocide and how his camera is changing the course of a nation.

“Every perpetrator is human," Joshua Oppenheimer says about the killers in his new documentary, The Look of Silence. "And if we want to understand how human beings do this to each other, and how they live with what they’ve done, we have to try to understand them as human beings.”

The Look of Silence opened nationally on July 31st.
